It has long been known in some circles that the CIA appropriated the term Conspiracy Theory (if it did not, in fact, invent it) to disparage and marginalize the critics of the Warren Commission Report.

The document 'educated' CIA employees on the 'correct' responses to criticisms of the Warren Commission Report and was an unabashed attempt to manipulate public opinion via the press (the CIA doesn't hold 'pressers', thus their information channels are usually through front companies and anonymous sources).

Regardless of the veracity of the Warren Commission Report, the document is emblematic of the culture of presumed superiority present in the government and intelligence communities during that era – after all, this is the same CIA that was conducting uncontrolled experiments on unsuspecting human subjects at the same they were touting their infallibility (is there any reason to believe things have changed?) The language of the CIA Dispatch dated 1 April 1967 (FOIA Document #1035-960) is clinical and dispassionate, but that has the inverse effect of contributing to the smugness of its message.

Skepticism is a vital tenet of a republican government and the inability to question a government's actions, motives, and processes is the hallmark of monarchies and dictatorships.
